> Can these metadata columns utilize normal column properties, like ordering equivalences, constantness, distinctness etc.? For example, AFAIU rowid is an ordered column, and if I sort the table by rowid, the SortExec would be removed? (it seems to me not yet at this point) Can we iterate over the design to support those capabilities, too? I with this PR a custom table provider that was ordered by row_id could communicate that information to avoid a SortExec From what I can tell, the metadata columns is only a notion in the `LogicalPlan` Specifically, the `ExecutionPlan` returned by the provider is no different than any other `ExecutionPlan` so it can communicate sortedness via `ExecutionPlan::properties` as normal -- This is an automated message from the Apache Git Service.
